JARRETT, OF BUCKNER, VIRGINIA ADVERTISING DEVICE Application filed February 11, 1930. Serial No. 427,555.

This invention appertains to advertising devices and more particularly to a novel window or store display for attracting the attention of prospective buyers.

One of the primary objects of my invention is to provide a miniature aeroplane exhibit in which the aeroplane is supported for rotary movement and is provided with an electric motor for driving the propeller, whereby the aeroplane will be caused to maintain a circular path when the motor is in operation, the plane being of such a character as to carry a suitable advertising sign or the like.

Another salient object of my invention is the provision of a novel bearing for rotatably supporting the aeroplane either from an overhead ceiling bracket or floor standard, the bearing having associated therewith in a novel manner the radially extending arm carrying the aeroplane and the non-conducting disc for supporting the annular contact rings for conducting the current to the motor of the aeroplane, the rings being adapted to be engaged by the roller contacts of the stationary supporting bracket.

A further important object of my invention is the provislon of a novel means for forming the inner and outer contact rings, one of,

the rings being provided with a depressed groove or track for receiving one contact roller and the other ring having an upstanding guard flan e for engaging the other contact roller, the ange acting as means for holding the rollers accurately positioned relative to the contact rings.

A further salient object of my invention is the provision of means for forming the body plate or fuselage of the aeroplane, the body plate being provided with a cut out portion adjacent to its forward end for receiving the electric motor, the motor being provided with a holding strap provided with ears for engaging the opposite faces of the body plate, the strap forming an efficient means for holding the motor in place and accurately disposed relative to the longitudinal axis of the plate, whereby the propeller driven directly from the armature shaft of the motor will be correctly centered, the strap also allowing the qiliick assembling of the motor with the aeroane.

A still further object of my invention is the provision of an improved miniature aeroplane advertising device of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings Figure 1 is a side elevation of my improved device, showing the aeroplane in front elevation and partly broken away.

Figure 2 is a section taken on the line 2-2 of Figure 1 looking in the direction of the arrows showing the aeroplane in side elevation, the rear end'of the aeroplane being broken away.

Figure 3 is a transverse section through the aeroplane taken on the line 33 of Figure 2 looking in the direction of the arrows illustrating the novel means for associating the electric drive motor for the propeller with the aeroplane.

Figure 4 is a top plan view of the ceiling bracket and novel bearings for supporting the aeroplane.

Figure 5 is an enlarged vertical section through the supporting bracket and novel bearings taken on the line 55 of Figure 4 looking in the direction of the arrows.

Figure 6 is a horizontal section taken on the line 66 of Figure 5 looking in the direction of the arrows illustrating the novel contact rings.

Figure 7 is a horizontal section taken on the line 7 7 of Figure 5 looking in the direction of the arrows, illustrating the novel means of securing the arm to the bearings, and

Figure 8 is a vertical section taken on the line 8-8 of Figure 5 looking in the direction of the arrows illustrating one of the contact rollers and its contact ring.

'The forward :1 body plate e6 is provided with a;

this arm is secured I 0 in any desired Way such'as by a suitten the body plate 46 and the attaching feet 56 and serve the dual function of tightening the band about the motor and holding the motor on the body plate. By this construction I am enabled to easily and quickly connect the motor with the body plate and at the same time centralize the same relative to the longitudinal axis of the aeroplane.

Connected with the inner and outer contact rings 26 and 27 and imbedded in the plate of insulation 25 are the feed and return wires 58 and 59 which may or may not be led through the hollow supporting arm 36. These wires extend down over the connecting rod 39 and terminate in a suitable plug 60, which is detachably connected with a suitable socket 61 connected with the feed and return wire 62 of the motor 51. By this arrangement the feed wires can be readily disconnected from one another when it is desired to detach the aeroplane from the connecting rod 39.

In order to connect the rod 39 with the aeroplane 45 I employ an eye bolt 63 which extends through a suitable opening formed in the body plate 46, which opening communicates with the cut out portion 50. The rod 39 which can be formed of metal is bent through the eye 63 as at G l and a thimble (35 is slid down over the rod and the bent back portion 64: thereof In use of my improved device the var ous parts are assembled as shown and described and when the current is turned on through the motor 51 the propeller 53 will be revolved thereby which will draw the aeroplane through the air in a circular path due to the connection of the aeroplane with the shaft 10. As the aeroplane gains speed the centrifugal force tends to swing the links 39 outward on the pivot 40 the speed of the aeroplane and the sizes of the propeller determining the amount of outward swing of the aeroplane. The opposite sides of the body plate 46 of the aeroplane can be provided with suitable advertising matter and as the aeroplane revolves the same will attract the attention of passers by and to the advertising matter carried thereby.

I lay partricular stress on the formation of the hub 18 and the means of attaching the supporting arm 36 and the insulating disc 35 as well as the formation of the contact rings 26 and 27 and the contact rollers 32 and 33. Likewise I lay stress on the arrangement and the means of connecting the drive motor with the body plate of the aeroplane 45.

Changes in details may be made without departing from the spirit or the scope of this invention, but

\Vhat I claim as new is:
